[dvs] carbon footprint calculators

[WJ Marston LEED AP]

James Wurster posted a good question!

Bot NB: Of course no single calculator can truly measure everything  
accurately because who knows where to stop, or what to include, or  
how to incorporate things that haven't happened yet... so there  
simply can't be an "absolute best" one for every purpose...  yet!

I've been happy with Native Energy's calc although haven't used it in  
quite a while:

Here's a bit ABOUT carbon footprint calculating, ending with a link  
to the google one, rooted in GIS map data.
